To all fwioml t may concern: x

Be it known that I, Ti-rnononn citizen of `the United States, Aresiding1n Floral Park, Long VIsland, New York, have 5 invented certain new anduseful Improve ments in Concrete Construction,A of which the followingis the specification.

My inventionrelates to the elimination in concrete construction oftheuse of a tempoand Vreinforcing being combined into a single structural,lmember w-hichperforms the functions of both'. This is accomplished insuch a manner that the concrete may still be poured as in the-'case ofthe previous type of construction in which temporary molds wereutilized. `lnmy improved construction I use as the combinedmoldandreinforcement a reticulated structure, preferably in the foim ofa coarse wire .2O screen, 'the interstices of which are suffi,-`

ciently large to perin't the finer grade of concrete to pass through butobstructing the passage of the coarser concrete therethrough andthereby' embed the mold, thus converting it into apermanent'reinforcement.

n the construction of the concrete structure of the present invention, ahole is first dug having a wall, thereupon a reticulated structurels in'30 serted into the hole to forni with the lateral `Wall of said hole anannular space, and

thenA concrete is poured' into the annulary space thus formed, whereuponthe liner concrete will pass through the interstices of said wall, toprevent the passage of the.

coarser concrete therethrough and the finer concrete which is disposedon the inner face of the reticulated structure, then smoothed downifdesired to form a iinished inner face 40 for the Wall beingconstructed.l The reticulated member particularly adapts itself first lv to serve as a mold face in the construction of the concretestructure,thenx to permit its' being. embedded 1in theconcrete yto subse- I'45*.quently serve asa permanent reinforcement for the structure whencrlrnpleted, and fur- A therinore to' coperate with the concrete itselftolretain the coarser concrete where most required for the stability ofthe structure and to'permit' the automatic distribution of the'nerconcrete sov that it can'lbe utilized to the best advantage, namely, tobe quickly formed into a finished inner face for the completedstructure.

When the heightof the tank is considerable,

it may be advi-sable to use temporary reinforcing means forthe screen,such as naru V row hoops`8, the ends of which overlap, as

shown in Figs. 1 and 2, and which maybe -secured together by means ofthebolts,9.

crete mixture through the mesh of the fabric at the points where theyare temporarily situated does not weaken the reinforcing action ofthewire mesh upon the concrete to any appreciable exten-t.

After the wire mesh has been erected in i lace as shown in Fie. 1 acrown iece'for the structure is mounted uponv it. This crownpiecepreferably consists of four sheet metal segments 10 which overlap attheir edges and are secured together by the bolts 11, thus forming afrusto-conical member. Around the bottom periphery of this member areformed a plurality of inturned lugs 12 formed by slitting the metal at13 and l-l and then bending the lugs 12 inward. When the crwnpiece is inposition, these lugs are substantially vertical and abut against theinner surface of the wire fabric, as-clearly shown in Figs. 1 and 2.\Stove bolts 15 may be passed tluoughsuitable holes in these lugs andthrough the wire mesh, thus clamping the crownpiece firmly upon .thewire fabric. At is upper edge the crownpiece is secured to a manholecollar 16, which is provided with an outwardly and downwardly slopingflange 17in line with the crownpiece and to which it is attached bymeans of the bolts 18. The upper periphery of the manhole collar isprovided with a horizontally eX- tending' flange 19, adjacent to whichis an inwardly extending flange 20 forming a seat for the cover'21.

1 In Fig. 1 I haveshown' the molds in place 'for the construction of asewage disposal plant comprising a liquefying tank at the to describethe structure in left and a lsiphon chamber at the right, together withthe necessaryinlet siphon and discharge pipes, but it will not benecessary detail, since my invention is directed to the concreteconstruction. Fig. 1 shows a small amount of concrete G to have beenpoured into the space 5 between the mesh and the earth wall. Incompletlng the structure the concrete is poured in until this spacebetween the wire mesh and the ground is completelyl filled and theconcrete is then carriedup along the dotted lines 22 in Fig` 1, forminga conical tanks and thel like,

, lated member,

construction or crown, this part of the com crete being retained inposition while hardening by the sheet-metal crownpiece.

It will be seen that the construction above described provides anefficient knockdown combined mold and reinforcement for conas it do'es,acombined mold and reinforce- 1 ment entirely constructed of sheet metalor wire screen is lifht sim le and-may be packed ,for shipment in smallcompass, and Y requires no iexpert erector to put it in place.

Furthermore, its use is superior to concretetanks formed with Wooden, orother molds,

yiirwhich there is no reinforcing provided,

since the wire mesh adds a considerabledegree of strength to thestructure when it becomes embedded in the concrete as thel latter setsor hardens.
